连词but和although/though连接了对比的观点。Whereas也可以用，但不常用:
The new city hall is amazing but it’s going to cost a lot.
He’s quite short, whereas his sister is tall.
But
But是一个协调连词，用来连接不同的观点。并列连词将语法类型相同的词连接起来。
main idea | contrast | |
The meal was good I want to lose weight Lara cooked roast beef for me Edinburgh is an interesting place | but | expensive. I hate diets. I don’t eat meat. it takes a long time to get there. |
注意:
我们不能用however作为连词来代替but来连接单词和短语:
My teacher is very nice but a bit strict.
Not: My teacher is very nice however a bit strict.
Although/though
Although/though可以用来对比观点。Although/though是从属连词，用于连接从句和主句，如after, as, before, if, since, that, even though, even if。
main idea | although though | contrast |
Grace is an excellent athlete | she injured her leg recently. | |
Harry is a great friend | we don’t see each other often. |
although/though 的从句可放在前面.
Although Though | contrast | main idea |
the car was destroyed, | no one was injured in the crash. | |
people say it’s dangerous, | I think it’s an amazing country. |
But or although?
But不能和although/虽然一样使用。我们用but来连接语法类型相同的词(并列连词)。
注意:
由并列连词连接的从句的顺序不能颠倒:
Although it rained a lot, we’ve still enjoyed our holiday.
We’ve still enjoyed our holiday, although it rained a lot.
It rained a lot but we’ve still enjoyed our holiday.
Not: But it rained a lot, we’ve still enjoyed our holiday.
Although听起来比but更正式。Though在口语中比在书面语中更常见。Although在写作中比在口语中更常见。
Even though, even if
Even though和Even if也用作从属连词，与although/though的用法相同。Even though和although很相似，但它形成了更强烈的对比:
Even though I cycle to work, I don’t feel very fit.
Even if 含义是 ‘whether or not’:
Even if you run, you’ll still be late. (You’ll be late whether you run or not.)
I feel tired even if I go to bed early. (I feel tired whether I go to bed early or not.)
